Kenworth offers UltraShift PLUS VAS transmission for select medium duty trucks

KIRKLAND, Wash. – Kenworth announced this week that it is now offering the 10-speed Eaton UltraShift PLUS VAS transmission for its T370, T440, and T470 with the 8.9 litre Paccar PX-9 engine.

According to Kenworth, the Eaton UltraShift PLUS provides operators of select Kenworth medium duty trucks with an alternative to traditional manual or automatic transmissions while expanding available application use.

The transmissions are recommended for construction, refuse, and agriculture applications. It incorporates an electronic clutch actuation system that enables quick shifts and clutch engagement, regardless of engine RPM.

“Kenworth has an excellent partnership with Eaton, and our medium duty truck customers will benefit from the performance and value of the Eaton UltraShift PLUS VAS transmission option for the Kenworth T370, T440 and T470,” said Kurt Swihart, Kenworth marketing director.

In addition, the system automatically selects an appropriate start gear and adapts shift decisions based on driving environment and also features Hill Start Aid, creep modes, auto neutral, and engine and clutch over speed protection.
